Spring care starts with recognizing that your plants are changing, and following their lead. The signs come gradually: dormant plants push fresh leaves and shoots, deciduous plants leaf out, and growth that stalled all winter visibly accelerates. As with fall, the calendar is only a rough guide — it’s the plants and the weather that tell you the season has truly turned, and in Southern California that awakening often begins as early as February.

Let those signals set your pace. When you see genuine new growth, it’s the plant announcing that it’s ready for more water, more food, and more of everything that supports growth — the cues to begin ramping your care back up from winter’s minimum. A plant still sitting dormant, by contrast, isn’t ready yet, so watch each plant rather than treating the whole collection identically.

Early spring is a transition, so expect some overlap with winter: cool, damp spells and even a late frost are still possible, especially in the first weeks. Ramp up gradually and stay ready to protect tender new growth if a late cold snap arrives — those fresh shoots are the most frost-vulnerable part of the plant.

Spring reverses fall’s wind-down: as growth accelerates and the weather warms, your plants need progressively more water. Actively growing plants drink far more than dormant ones, and as the season’s rains taper off toward the summer dry season, you steadily take back over as the main water source. The shift is gradual — early spring may still lean on rain and cool damp soil, while late spring starts to feel the first real heat.

Let the soil guide the increase, as always. Check with a finger and water when the top inch or so has dried — and you’ll notice that interval shortening week by week as growth and warmth ramp up. Container plants lead the way here, drying faster than the ground and needing that increasing frequency sooner. Keep watering deeply so the whole root ball is wetted, encouraging the strong, deep roots that will carry plants through the summer ahead.

By late spring, watch for the season’s first heat spells, which can arrive suddenly and catch a garden still on a gentle spring schedule. Treat an early hot stretch like a preview of summer — water more, and more deeply, and don’t let fresh new growth wilt. As the heat builds toward summer, our summer care guide takes over.

Here is the heart of spring care: feeding resumes. The golden rule of fertilizing is to feed only during active growth, and spring is exactly when that growth returns after the winter pause. A plant surging with new leaves and roots is genuinely hungry, and this is the season it can actually use what you give it — making spring the single most important time of year to feed. Potted plants need it most of all, because frequent watering constantly flushes nutrients out of their limited soil, and unlike plants in the ground, they can’t draw on the surrounding earth to replenish.

A few principles keep feeding safe and effective. Start when you see new growth, and begin gently — use a balanced fertilizer, and for potted plants especially, dilute it to about half strength, since containers concentrate fertilizer salts far faster than open ground and are easily overdosed. Always feed onto already-moist soil, never a dry root ball, so the fertilizer can’t burn tender roots. From there, a slow-release feed worked into the mix or a diluted liquid feed every few weeks through the growing season keeps plants supplied without overwhelming them.

Match the feed to the plant, because not all of them want the same thing. Leafy and flowering plants appreciate regular feeding — a balanced formula for general growth, or a higher-phosphorus one to encourage blooms. Succulents and cacti want far less: a diluted, occasional cactus feed at most. And California natives, adapted to lean local soils, need little or no fertilizer at all and can actually be harmed by rich feeding — for these, restraint is the correct approach. When in doubt, under-feed rather than over-feed: too much fertilizer produces weak, sappy growth and salt buildup, and does more harm than too little.

Spring is a prime season for planting, repotting, and dividing — and for containers especially, it’s the ideal moment to give plants fresh room to grow. As plants wake and push new roots, they establish quickly into new soil and new pots, using the whole growing season ahead to settle in. This is the time to move root-bound plants up a pot size, refresh spent potting mix, and divide overgrown clumps while their energy is rising.

When you pot up, move only one container size larger at a time. An oversized pot holds a large volume of slow-drying soil the roots can’t yet use, keeping the mix wet too long and inviting rot — a step up of an inch or two of extra width is plenty. Use a quality mix suited to the plant type (gritty and fast-draining for succulents, richer and more moisture-retentive for leafy tropicals), and make sure every pot drains freely. Water in a newly potted plant, then keep it attentively but not excessively watered while its roots spread into the fresh soil.

Remember the link to feeding: fresh potting mix already carries several weeks’ worth of slow-release nutrients, so a freshly repotted plant does not need fertilizer right away — wait until it’s settled and actively growing before you begin. And in early spring, keep one eye on the forecast: hold off major planting or root disturbance right before a late frost or a sudden heat spell, giving fresh plantings the mildest possible start.

Spring is when the pruning you held off through winter can finally happen. Now that the danger of frost is passing, it’s safe to cut back the frost-sensitive plants you protected over winter — and to remove any frost-damaged foliage you deliberately left in place, since it’s done its protective job and fresh growth is ready to replace it. Pruning now, as growth resumes, lets the plant channel its spring energy into strong, well-placed new shoots.

For flowering plants, timing matters: prune spring bloomers after they finish flowering rather than before, so you don’t cut off the coming display, while many other plants are happily shaped as they push their first new growth. Use clean, sharp tools, remove dead, damaged, or crossing branches, and shape while you can clearly see the plant’s structure filling back in.

It’s also the moment for a general cleanup after winter: clear away dead leaves and debris that accumulated in and around pots, refresh mulch, and tidy edges. This isn’t just cosmetic — removing decaying material reduces the fungal problems and pests that overwintered in it, giving the new season’s growth a clean start. Our guide on pruning like a professional covers the clean-cut principles that apply here.

Spring plants are growing fast, which means both good signs and problems show up quickly. Learning to read them lets you feed and water in step with what each plant is actually doing, and catch the season’s missteps — usually overfeeding or a late cold snap — before they set the plant back.

Keep an eye out for pests, too: as tender new growth appears, so do the insects that love it — aphids in particular flock to soft spring shoots. Catch them early, while populations are small, and the flush of new growth stays clean and vigorous.

Spring’s problems come from the season’s surge of growth and its lingering transition weather — overfeeding, a late frost, an early heat spell, and the pests that wake with the plants. The grid below covers what to watch for.

Spring care is about supporting a surge of growth: feed it, water it, give it room, and stay alert to the season’s transition weather. Here’s the rhythm of a well-run Southern California spring.

As plants show new growth, ramp your watering back up from winter’s minimum — checking the soil and shortening the interval as warmth and growth build, and watering deeply each time. Bring the fertilizer back out: begin feeding when you see new growth, use a balanced feed at about half strength for pots, apply it onto moist soil, and match the amount to the plant — generous for leafy and flowering plants, sparing for succulents, little or none for natives. Take advantage of prime planting season by potting up root-bound plants, refreshing mix, and dividing clumps — then waiting a few weeks to feed anything freshly repotted.

With frost passing, do the pruning you held off all winter, cut back frost-protected and frost-damaged plants, and clean up the debris that overwintered in your pots. Stay watchful of the transition weather — a late frost early on, a first heat spell later — and of the pests that wake with the new growth, catching aphids and mites while they’re few. Do all that, and your plants head into summer strong, well-fed, and established.

Spring is the season a Southern California garden has been building toward all year. Everything that came before — the summer survival, the fall wind-down, the winter rest — was in service of this moment, when plants throw themselves back into growth and the gardener finally gets to nurture rather than merely protect. It’s the most hands-on and most rewarding stretch of the year, and it rewards enthusiasm tempered with a little care.

The through-line is to support the surge without overdoing it. Feed the growth, but at half strength and onto moist soil; ramp the watering up, but let the soil set the pace; plant and repot freely, but wait to feed the fresh soil; prune and clean up, but mind a late frost. All of spring’s tasks are variations on one theme — meeting your plants’ rising energy with matching, measured care.

Do that, and you set up the entire year. Plants that are well-fed, well-watered, freshly potted, and cleanly pruned in spring enter summer strong enough to withstand the heat, and the annual cycle comes full circle. A thriving spring is the foundation everything else is built on — and in our mild climate, it’s a genuine pleasure to tend.
